摘　　要：无线传感器网络中节点的自身定位是其大多数应用的基础,文章利用网络中存在的冗余信息,针对客观存在的不良节点,对现有分布式无需测距技术的Amorphous定位算法进行改进,以提高整个网络的平均定位精度。仿真结果表明,改进后的算法有效地降低了节点位置的平均估计误差。该算法无需任何附加的硬件支持和良好的拓展性,对实际的应用具有积极的意义。Self-location algorithm for wireless sensor networks （WSN） is the basis of many applications. In this paper, for the purpose of improving the average positioning accuracy, an improved Amorphous algorithm is described on the basis of using the network redundant information focusing on the faulty nods. The simulation result shows that the improved algorithm reduces the average error of the nods greatly. It is applicable because there is no need to add any more hardware to the network.
